Wyoming Contractor License Requirements

The State of Wyoming does not issue a statewide general contractor license or residential home builder credential. Contractor licensing, trade testing, and building permits are delegated to municipal and county building departments under Wyoming home rule.

Contractors must register and obtain municipal licenses in each city or county where they construct or remodel buildings.

Incorporated cities enforce local contractor classifications:

• Class A General Contractor: Unlimited commercial and residential building construction
• Class B Building Contractor: Residential construction and light commercial structures
• Class C Specialty Contractor: Specific trades including roofing, plumbing, and HVAC

Municipal licenses require passing ICC contractor examinations, proof of general liability insurance, and workers' compensation.

The Wyoming Department of Fire Prevention and Electrical Safety — Electrical Division exercises exclusive statewide licensing authority over electrical contractors. Contracting businesses must employ a full-time licensed Master Electrician of record.

• Initial license fee: $400 ($150 annual renewal)
• State electrical wiring permits and code inspections mandatory
• Individual electricians on site must hold Journeyman or Master licenses

Building, roofing, and plumbing permits are issued by municipal and county building departments. For electrical work, permits are pulled directly through the State Fire Marshal Electrical Division (unless within a certified local inspection program).

Under Wyo. Stat. Title 27 Chapter 14, Wyoming operates an exclusive monopolistic state fund. All employers engaged in extrahazardous construction trades (including all building, remodeling, roofing, electrical, and plumbing work under Wyo. Stat. § 27-14-108) must obtain workers' compensation coverage through the Wyoming Department of Workforce Services. Private workers' comp insurance policies are statutorily invalid for extrahazardous trades.

Under Wyo. Stat. § 39-15-306 and § 27-1-106, out-of-state contractors entering Wyoming to perform construction must register with the Department of Workforce Services and Department of Revenue, and post a surety bond (or 4% contract deposit) guaranteeing worker compensation and tax payments.
